MOTOR-CYCLE SEAT.

Specification of Letters Patent.

Patented June 29, 1915.

Application filed March 20, 1914. Serial No. 825,974.

. TO aZZ whom it may concern Be it known that I, BERT S. CHILsoN, of Fayetteville, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Motor- Cycle Seats, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in seats, and more particularly to a seat for a motor cycle or other like vehicle.

In the use of motor cycles and similar vehicles, it is very desirable and convenient to be able to carry two people, and heretofore supplementary seats have been used for this purpose and positioned at difierent places upon the frame of the motor cycle, somev times in front of, but more often to the rear of, the regular seat. This tandem arrangements of the seats is very unsatisfactory, particularly for the reason that the passenger using the supplementary seat is compelled to face at right angles to the direction of movement of the vehicle and the practical effect of this is that if the motor cycle tips over in a direction away from the one in which the passenger is facing, the passenger is thrown over backward and is unable in any manner to save himself or to break the abruptness of the fall. Further, the back of the person sitting upon the regular seat is directly toward the passenger, which is also a very unsatisfactory arrangement.

The primary object of my invention is to produce a motor cycle seat adapted to carry two people, both facing in the direction of movement of the vehicle and positioned side by side upon opposite sides of the frame.

A further object is to provide a seat which is so constructed that it may be provided with spring upholstery without raising the position of the seat occupants above the normal and desirable plane.

A further object is to construct the seat so as to have a three-point bearing upon the motor cycle frame, preferably as shown, a forward bearing centrally, of the frame and two opposite rearward bearings disposed at opposite sides of the frame. i

Other objects relate to the particular form of the seat and in providing the body portion or frame of the seat with a substantially centrally arranged longitudinal rib and a plurality. of cross ribs terminating at or merging into the longitudinal rib, and likewise merging into the edge of the seat frame and enlarged at the curved or angular portions of the frame to provide a maximum strengthening and reinforcing means.

In the drawings-Figure 1 is a side view of a portion of a motor cycle equipped with this invention. Fig. 2 is a cross section on line 22, Fig. 1. Fig. 3 is a central, longitudinal cross section of the seat frame showing the longitudinal reinforcing rib in full. Fig. t is a view similar to Fig. 2, showing ailightly different form'of reinforcing cross r1 s.

The invention comprises a seat frame or body portion formed with a central flat upper portion 1 and substantially flat end portions 2 and 3, depressed some distance below the plane of the face 1 and adapted to receive suitable spring seats or other cushioning members -4- and -5', respectively, of sufficient thickness so that their top surface preferably lies in substantially the same plane as the plane of the face 1. Preferably, the ends -2- and -3- have attached thereto suitable platelike members -6 and 7 by means of bolts or screws -8- and -9, respectively, and to these members --6 and 7 the cushioning members or spring seats are attached.

The body portion or frame of the seat is preferably an integral casting and is formed with a suitable central longitudinal reinforcing rib 10- of sufficient width at its front to suitably reinforce the projecting member 11 provided with an opening 12 for engagement with the usual post 13 of the motor cycle frame, and this rib l0 gradually narrows toward its rear portion until it merges into the rear edge of the frame. The body portion is also formed with suitable cross ribs 14: merging into the edge of the depressed portions 2 and 3- and gradually widening toward the curved or angular corners l5 and 1G, and extending upwardly of the sides -17 and 18 of the frame and across the under side of the top 1-, merging as shown in Fig. 2 into the longitudinal rib -10, or as shown in Fig. 4:, merging the seat at three points.

into the top 1 directly at the base of the rib l0. The body portion of the seat is also formed with suitable supporting members l9 and 20 preferably disposed at opposite sides of the central rib 10 and, therefore, at opposite sides of the engaging opening -12- of the projection l1 and adapted to form, in connection with the opening 12- engaging the post 18-, a three-point bearing for the seat, and for this purpose these supports are of suitable length and suitably disposed so as to engage the plate l2 supported by the springs -22- upon opposite sides of the vehicle wheel 23 and so positioned as to abut against the bifurcated brace member 24: attached to the plate -2l-, in such a manner as to prevent lateral movement of the seat. It will be apparent in this con nection that although I have described and shown a particular arrangement of these supports in connection with a particular construction of frame support for the motor cycle, that the essence of this portion of the invention lies in a three-point support for the seat and that the relative position, arrangement and size of these supports and the parts of the frame with which they contact may be varied at will, without departing from the spirit of this invention, so long as means is provided for supporting In the particular form of motor cycle shown, the frame 27 is supported at the rear entirelyby the springs 22 and the spring seats 4- and 5- are not so essential as in connection with rigidly sup ported frames, and it is readily apparent that particularly in connection with spring supported frames, the spring seats or cushioning members may be omitted, without affecting the usefulness or operativeness of the structure.

The side walls 17 and 18 are, as shown, preferably widened intermediate the section 1 and the depressed ends -2- and 3 respectively, to form forwardly and rearwardly projecting flanges -25 and 26 merging into the relatively large flat, depressed ends 2 and 3 and the reinforcing rib upon each of the rearward flanges 25 merges at its ends into the seat frame and the forward or front reinforcing rib extends upwardly to reinforce the projection 11 and the flange 26.

It will now be apparent that many changes may be made in the details of construction and arrangement and in the particular form of thedevice, without departing from the spirit of this invention as set forth in the appended claims.
